At six-feet, eight-inches tall he was, and still is, the tallest NFL player to ever play at the wide receiver position.
And no Eagles fan will ever forget seeing him unfurl the wingspan on that 6' 8" frame for a touchdown spike that would put Gronk to shame.
And he did it plenty of times. 79 times to be exact in a 14-year old NFL career, thirteen with the Philadelphia Eagles between 1971 and 1983.
Harold Carmichael will be enshrined in the National Football League (NFL) Hall of Fame in Canton, Ohio as part of the Centennial Class of 2020.
Big #17's career totals are 590 receptions for 8,985 yards and 79 touchdowns and he was THE dominant wide receiver in the decade between 1973 and 1983 when he led all receivers in all three of those categories.
And he did it during some lean years in Eagles football. The 1972 Birds finished 2-11-1.
But Carmichael stayed with the franchise and was rewarded with a trip to the Super Bowl in 1980 under coach Dick Vermeil.
Between 1972 and 1980 Carmichael set a then NFL record with a pass reception in 127 consecutive games.
When he broke the old mark of 105 in 1979 the Eagles presented him with a 12-foot high trophy.
Then general manager Jim Murray said it was "the world's tallest trophy in honor of the of the world's tallest receiver."
Better make that gold jacket in extra long.
Enshrinement ceremonies in Canton are from August 6 - 9, 2020.
